xwllz — Attack-surface management for blue teams

xwllz is a CLI for discovering, monitoring, and reporting on your own external attack surface. It maps the domains, subdomains, IPs, services, certificates, and exposure points an attacker can reach — so blue teams can see their perimeter before attackers do.

How it works

xwllz is pure Python by default — no system binaries required. It detects optional accelerators (nmap, masscan, rustscan, nuclei, httpx, dnsx, dig) on your PATH and uses them automatically when present, and falls back to its built-in engines otherwise. Data is stored in SQLite.

The ASM loop

Each run produces a snapshot. xwllz monitor re-runs discovery and diffs against the previous snapshot, showing you exactly what's new, changed, or removed across your perimeter.

Quickstart

pip install xwllz

xwllz init acme --domains example.com,corp.example.com
xwllz discover acme
xwllz monitor acme        # re-scan and show what changed
xwllz report acme --format md

Data sources

Keyless by default: crt.sh (certificate transparency), DNS (A/NS/MX/SPF/DMARC/DKIM), HTTP probing, TLS/cert inspection, socket port scans.

Optional keyed enrichment (set env vars to enable):

Commands

xwllz init <org> --domains d1,d2      define the scope to monitor
xwllz discover <org>                  enumerate the attack surface
xwllz monitor <org>                   re-scan and report new/changed/removed
xwllz report <org> --format md|json|html
xwllz status <org>                    current surface dashboard
xwllz intel <indicator>               URL/domain/IP lookup
xwllz whois <domain>                  whois lookup
xwllz cert <host>                     TLS certificate details

Data is stored in SQLite at ~/.local/share/xwllz/xwllz.db.
